Don't forget that a human can turn their head, and bend forward
I have been paying a lot of attention to when I lean forward. Here's what I've found:
1) when looking leftward, leaning forward is useful if the A pillar is likely obstructing a good chunk of visibility
2) when looking rightward, leaning forward is useful if the passenger is flat-out blocking your view.
3) when the intersection has limited visibility due to shrubs, buildings, or how the road bends, etc., leaning forward does ABSOLUTELY NOTHING. We do it anyway in an attempt to gain visibility, so we might think it's helpful or more advantageous than a fixed camera. But it really isn't.
As for scenarios 1 and 2? Doesn't affect exterior cameras at all.
When it's an intersection with poor visibility, we inevitably have to creep into the lane, and that's the reason we find those intersections dangerous: we can't see until we're in an unsafe position. This is why you may see "blind driveway" or "vehicles exiting" signs on the main road. The car with the right of way needs to be cautious.
(speaking in general here, not specifically wrt Chuck's ULT, which IMO doesn't have a visibility problem)
